Recent advancements in Full Waveform Inversion (FWI) have resulted in algorithms to produce high resolution and high-fidelity velocity and density volumes. FWI velocity is used in migration to produce high quality seismic image of subsurface. Along with velocity and density products, FWI model Derived Reflectivity (FDR, also known as FWI Image) is being used as a product for seismic interpretation and reservoir characterization. FDR has proved a good tool to reduce subsurface uncertainties. Benefited from the contributions from all the arrivals in FWI input, FDR provides better illumination under complex overburden. However, amplitude of the FWI reflectivity is still questionable due to possible leakage/contamination of elastic properties (Vp, Vs, Density). This leakage of elastic properties can be overcome with the developments of multiparameter FWI and FDR based partial stacks. The multiparameter techniques have the potential to minimize uncertainties and risks associated with exploration, development, and production settings.

This workshop will cover workflows, methodology and examples to discuss the benefits and challenges in implementing FWI products in reservoir characterization:
• Improving structural interpretation
• Incorporating FWI models in seismic AVO inversion
• Investigating the amplitude fidelity of FDR, and
• Reservoir properties prediction from Elastic FWI
